I wonder what store they go to in order to find coyote piss and who manufactures it? Sounds like that could be a dangerous business. Why wouldn’t cat piss suffice, other than the smell?
Cat pee? You seen any rats lately? The ones around here chase the cats. You want a biiiiig predator. Cougar pee works well, too, if you can’t get coyote.
You can buy predator urine on Amazon or from most hunting/trapping outfitters. Predator urine can be used to repel garden pests or to mask human scent.
Maybe attaching that thing to hold replaceable dryer bars of the stuff in the engine compartment away from extreme heat to prevent any fires, and still get the benefit of repelling rodents.
Predator urine is good for chasing away little things that scare.
Damn squirrel here keeps eating tomatos...stole every single one off one plant.
He ain’t fooled by wolf pee.
